Mellitus was the first bishop of London in the Saxon period, the third Archbishop of Canterbury, and a member of the Gregorian mission sent to England to convert the Anglo-Saxons from their native paganism to Christianity. He arrived in 601 AD with a group of clergy sent to augment the mission, and was consecrated as Bishop of London in 604. Mellitus was the recipient of a famous letter from Pope Gregory I known as the Epistola ad Mellitum, preserved in a later work by the medieval chronicler Bede, which suggested the conversion of the Anglo-Saxons be undertaken gradually, integrating pagan rituals and customs. In 610, Mellitus returned to Italy to attend a council of bishops, and returned to England bearing papal letters to some of the missionaries.
